Patrick has appeared in such American television series as My Wife & Kids, CSI: Miami and Passions. From 29 June to 25 September 2006 he was part of the cast of the long-running soap opera All My Children playing the role of Jamal Cudahy. He has also played the lead role in an independent film "I Do, I Did" (2009).
Patrick announced on 13 September 2006, that he has left his role on All My Children, due to creative differences with the show. He is also on The-N television show, Beyond The Break.
On 11 May 2007, it was announced that he had joined the cast of Days of our Lives in the role of Jett Carver. His first air date was 1 June. However after five months he was fired. NBC declined to comment on the reasons for this, and his last appearance aired on 14 November 2007. Patrick himself has expressed the view that his dismissal was a consequence of an explicit photo shoot he completed in the September 2007 edition of Playgirl Magazine and the magazine website. Unusual for celebrity subjects, Patrick elected to pose full frontally nude for several shots, in darkened silhouette. He has also appeared on Just Jordan. Marcus reported to H8terade Radio in 2010, that he was unaware that full frontal would be showed, and even went as far as saying that Playgirl ruined his career.
Recently he was featured in RnB Singer Ashanti's music video for the song The Woman You Love.
Aside from acting, Patrick has had a singing career, firstly with the boybandWorlds Apart and then as a solo singer.
Patrick has practiced Tae Kwon Do, winning championships at junior and men's heavyweight level.
